能否同时将两个请求映射到单个无状态 EJB 实例
Can two request be mapped to a single stateless EJB instance concurrently
能否将两个请求同时映射到单个无状态 EJB 实例？
或者容器必须将请求映射到不同的实例或序列化请求？
This means, for example, that [...] the
container may interleave requests from multiple transactions to the same instance.
这听起来像是允许并发..
对有状态和无状态会话 bean 的请求必须由容器序列化。
这来自 EJB 3.1 specification 的第 4.3.14 节：
The container serializes calls to each stateful and stateless session bean instance. Most containers will
support many instances of a session bean executing concurrently; however, each instance sees only a
serialized sequence of method calls. Therefore, a stateful or stateless session bean does not have to be
coded as reentrant.
